WHISTLE.

Application filed October- 6, 1927. Serial No. 224344,

This invention relates to whistles and particularly to devices oi thisclass adapted to sheetmetal parts adapted when coupled together to termthe whistle, and sald parts being providedv withv means f'OIJDlEGllOOking the same one with the other and to provide a substantially air-ti htconnection be tween said parts; a further object-beingjto provide awhistle, the separate parts ofwhich are so coupled together as to permitof the uncoupling of said parts at will for the purpose of cleaning,whereby the whistle may be maintained in perfect, operative condition atall times; a further object-beingto provide one ofthe parts of thewhistle with extending, I in conjunction with the whi tle body, a fingerring or loop tor niounting the whistle upon the linger of awearer, -.thespring members iormingsaid loop adapting the whistle to lingers ofdii'l'erent sizes; and with these and other objects in view,ftheinvention consists in a device of the class and; for the purposespecified,which is simple in construction, eiiicient in use, and whichis constructed as hereinafter describedand claimed. 7

The invention "is fully disclosed in, the following specification, ofwhich the accompanying drawing. forms a part, in which the separateparts of my improvement are des-. ignated by suitable referencecharacters in each of the views, and in which-:

Fig. 2 1s a perspective view of one of the parts of the whistle deviceshown in Fig. ,1.

Fig. 3 is a perspective view of the other whistle part.

*ig. 1 is a section on the line 4 4 of Fig. 1; and, v g a Fig. 5 is aview similar to Fig. '1 but show ing a slight modification.

V In the construction shown in Figs. 1-to 4i inclusive, I employ two.whistle parts or bodies 10 and 11, thepart 10 constituting thecasingportion of the whistle and comprising a top wall 12, sidewalls13and anend wall 14:, forming at one end ofthe part 10, abox-shaped or eupshaped portion. The} top wall at the other end of thepart 10 extends in a lip portion 15 which curves onto'the sides 13, thelatter being cutaway as'showfn curved spring members forming othermovable member Q S.

at 13. The top wall is also provided'with an aperture 16 which extendsto a slightde onto both of t-heside walls 18, the aperture having astraight front wall 16 and an arc-shaped or curved rear wall 16 p in theconstruction shown, the side walls 13 are provided substantiallycentrally there oi with i lTwhich form, in conjunction with the body ofthe whistle, a linger ring or loop, in which a linger ofthe hand isadapted to be placed in mountiz the whistle on thehand. The inner facesoi the side walls 13, and the end wall 14 are provided with grooves 18,note Figs. 1 and t, which provide for the locking of the parts-11 inconnection with the part 10, as later described. i

The. part 1-1 is also fashioned from sheet metal and comprises a bottomwall 19, side walls 20' and an end wall 21 forming asubj stantiallybox-shaped end portion which is adapted to lit within the box shapedportion of the part 10 in themanner showninFigs. 1 and L of the drawing.lhe bottomwall member and, is curved upwardly and out wardly in the formof a lip portion 22 which epcnding curved spring members so 7 19 isextendedat the open end the box isin alinement with the curvature andinclirf nation of the side walls set out at 135*. Thislip portion isbentb k u itself as seen at 23 at the outer end of'the 26; whichfi itswithin the side walls 20, and

the end wall 21 forming between it and the top and side walls of thepart 10, a sound chamber 27 in which may be placed a ball or It will benoted thatthe member upward inclination forms; a contracted ,pas-

sage '29 adjacent the aperture 16 whereby the blast ofair'passed'intothe chamberBO lead ingto said passage willbe directedonto the curvedwall16 of the aperture 16 toproduce the proper whistle tone, part of theair entering the chamber 27 and agitating the ball 28 therein if suchball be employed. ltwill be understood that the height or inclination ofthe member, 2 L maybe variedto suit the I desired or required whistle tone or pitchu a The sidewallsQO and the end wall 21am providedwithoutwardly projecting beads 31,

which are adapted to operate in the grooves chamberl27 except outwardlythrough thedischarge aperture 16, whereby the full blast of air maybeutilized in producing the whistle sound or tone. I

i In Fig. 5 of the drawing, I have shown a slight modification whereinthe extension of the bottom wall 19 from the member 24, insteado'f beingin the form of a single arcsh'aped memberas the member 26, is fashionedinto two arc-shaped-members 32 and 33 forming within and between thewhistle parts,

' separate sound chambers 34 and 35 in which balls '36 and 37 may beplaced, the chamber 3% registering with the aperture 16, whereas.

the chamber .35 registers with another aperture 38 similar to theaperture 16 but arranged rearwardly thereof. Intermediate the chambers 31 and 35 is formed a supplemental contraction chamber 39 by anupwardlyinclined lip portion 40 to direct the air blown into the chamber 34 tothe aperture 38 and the chain- 'ber '35.

Aside fromthe structure above described, the whistle tone in Fig. 5*willbe the same as the whistle shown in Figs. 1 to 4: inclusive except thatif it be desired, the body of I the whistle shown in Fig. 5' may belonger.

This type of a whistle, will produce a dual ortwo-tone sound ascomparedwi'th the single tone or pitch sound of th'ewhist'le shownaswe'll as sanitary condition at all times; 1ft will-be understood thatthe 'part 11 is slid" into the part 10 by placing the beads'or provjecti'ons 31 in the'grooves18fat the inouth- I this purpose.

1 to l inclusive. 7 In" both forms of construction shown,1the

separate parts 10 and 11 of the whistle, may

bestamped or pressed from sheet metal into the desired tornnand saidparts coupled and uncoupled whenever desiredby virtue of theinterlocking means employed. Inthis way, the chamber or chambers withinthe whistle may be kept clean, and the inner surfaces of thewh-istlecleaned at all times, to maintain the whistle ina-properly functioningpie'cejend of the whistle and sliding the parts one upon the other untilthe bead ofthe end wallf21 enters the'groove 18 in the end wall 14. Indissecting the parts, the 'nailof a finger may be-placed between the endwalls 21 and 14 ora'knife or similar tool used for 'In all types ofwhistledevices, it is cont mon'lyexperienced that the 'sound chamberthereof as well as the air admission chamber in the mouthpiecebecomes-clogged with dust,

dirt and foreign matter, especially in carrying the same about in apocket when the same is not in use, or 1n the use of the device, the

collection of moisture from the mouth, in the device, renders the'samenot only inoperative but unsanitary, in e that the ability to thoroughlyclean tliewhistle is rendered impossible by virtue of the unit structurethereof. With my improved whistle-device, however,'these objectionablefeatures are obviated, and the whistle may be kept in a clean,

sanitary and operative condition at all times.

It will be understood that while I have shown a whistle of specific formand constructi'on, that my invention is not necessarily limited to thewhistleherein shown and described, and various; changes therein andmodifications thereof may be .made within the scope of the appendedclaims, without departing from thespirit of my invention, or sacrificingits advantages.
